Abstract

original image

The front cover shows the effect of chemical impurity on the charge generation in the donor phase and the electron transport in the acceptor phase of an organic solar cell. Using photoconductive atomic force microscopy in conjunction with transient absorption spectroscopy and charge transport study, Thuc-Quyen Nguyen and co-workers investigate on page 1706 whether differing impurity shapes may lead to different loss mechanisms.
